Gene Rv2448c
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Involved in translation mechanisms [catalyic activity: ATP + L-valine + tRNA(val) = AMP + diphosphate + L-valyl-tRNA(val)]. |
| Product | Probable valyl-tRNA synthase protein ValS (valyl-tRNA synthetase) (valine--tRNA ligase) (valine translase) |
| Comments | Rv2448c, (MTV008.04c), len: 876 aa. Probable valS, valyl-tRNA synthetases, equivalent to Q9CBY7|VALS|ML1472 valyl-tRNA synthase from Mycobacterium leprae (886 aa), FASTA scores: opt: 5181,E(): 0, (85.4% identity in 876 aa overlap). Also highly similar to others e.g. O06851|SYV_STRCO from Streptomyces coelicolor (874 aa), FASTA scores: opt: 2470, E(): 1.6e-143, (60.45% identity in 880 aa overlap); Q9X2D7|SYV_THEMA|VALS|TM1817 from Thermotoga maritima (865 aa), FASTA scores: opt: 2418, E(): 2.4e-140, (44.2% identity in 891 aa overlap); Q05873|SYV_BACSU|VALS from Bacillus subtilis (880 aa), FASTA scores: opt: 2063, E(): 1.4e-118, (46.08% identity in 894 aa overlap); etc. Contains PS00178 Aminoacyl-transfer RNA synthetases class-I signature. Contains probable coiled-coil from aa 810 to 846. Belongs to class-I aminoacyl-tRNA synthetase family. |

| Proteomics | Identified in the cytosol, cell wall, and cell membrane fractions of M. tuberculosis H37Rv using 2DLC/MS (See Mawuenyega et al., 2005). Identified by mass spectrometry in Triton X-114 extracts of M. tuberculosis H37Rv (See Malen et al., 2010). Identified by mass spectrometry in M. tuberculosis H37Rv-infected guinea pig lungs at 90 days but not 30 days (See Kruh et al., 2010). Identified by mass spectrometry in the culture filtrate, membrane protein fraction, and whole cell lysates of M. tuberculosis H37Rv (See de Souza et al., 2011). |
| Mutant | Essential gene for in vitro growth of H37Rv in a MtbYM rich medium, by Himar1 transposon mutagenesis (see Minato et al. 2019). Essential gene for in vitro growth of H37Rv, by analysis of saturated Himar1 transposon libraries (see DeJesus et al. 2017). Essential gene by Himar1 transposon mutagenesis in H37Rv strain (see Sassetti et al., 2003). Essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011).
